No action without talk? UN peacekeeping, discourse, and institutional self-legitimation

In this article, I argue that much of the discourse observable within the UN constitutes neither unnecessary and unproductive 'talk' nor efforts to convince outside audiences of its legitimacy, but actually a form of institutional self-legitimation that is key to its ability to function. Using the case of the UN's Department of Peacekeeping Operations (DPKO), I show that because the organisation has a multifaceted organisational identity, it faces situations where it is forced to choose between multiple but equally appropriate courses of action, and it uses self-legitimation alongside other mechanisms to overcome these tensions. I specify three sets of circumstances in which this occurs, showing how DPKO uses discourse thatsimplifiesandexceptionalisesin a bid to reconcile or downplay these contradictions and reassert a cohesive and legitimate organisational identity internally. This simplification and exceptionalisation in turn serve anenablingfunction, allowing DPKO to continue operating in conditions of complexity by decreasing risk aversion and instilling a deep sense of professional loyalty in staff. At the same time, such discursive processes are costly and may entrench inefficient practices, rendering the effects of self-legitimising discourse paradoxical: they may enable action, but they reduce the efficiency and effectiveness of that action.
